This bug was moving very quickly across our cement patio to our bermuda grass lawn about 8:30 am, April 23, 2009. It has a very round back and head. It is mottled black with yellow, head is solid yellow; underbelly is shiny black. It appeared to be climbing stalks of grass, possibly nibbling on the ends; it tumbled off the stalks often, moving on to other pieces of grass. It moved almost too quickly to get a clear photo.

Hi Julia,
This is a Desert Spider Beetle or Inflated Beetle, Cysteodemus armatus, one of the Blister Beetles.  According to BugGuide, it is found in Arizona, Nevada and California.  Spring is the time of year we get the most Blister Beetle reports, and a relative, the Master Blister Beetle, is our Bug of the Month.
